objective: in this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) chironomid larvae were examined. methods: for this purpose, 2.5 grams of food per coconut considered in the period, with three replicates and chironomid larvae during the period of 15 days in plastic pans were kept in nut...

introduction: fasting during ramadan is a religious obligation for healthy adult muslims. this study aimed to investigate the effects of ramadan fasting and physical activity on blood hematological and biochemical parameters in male and female subjects. methods: in this study, 50 healthy subjects were randomly assigned to four groups: male control fasting (mcf) group (n=13), male training fasti...

in the present study, the age- and sex-specific changes of various haematological and blood serum biochemical blood parameters of beluga ( huso huso ) were investigated. blood samples were collected from 4-, 6-, 7-, and 8-year-old beluga (n = 7 for each sex and age). the specimens were fed at a rate of 0.5-3% body weight per day. ast and ldh levels in 7- and 8-year-old fish of both sexes were s...

background: lead is the oldest known toxic metal, physiologically and biologically harmful to living creatures. this study aimed to evaluate the lead accumulation in the liver and breast muscles of japanese quail (coturnix japonica) and to compare concentrations in both sexes and its effect on blood biochemical factors. methods: twenty-four young farm japanese quails (25 day old) prepared from ...

background : present investigation is based on the clinicopatho-biochemical alteration related to natural tick borne bovine babesiosis in punjab state. methods : blood samples from jugular vein of 542 bovines (cattle 466 and buffaloes 76) having history of tick in­festation, fever, hemoglobinurea or anemia were collected and tested for babesia bigemina by blood smear examina­tion and pcr target...

Understanding virtually any process in cellular and molecular biology depends on knowledge of the rates of the biochemical reactions, so it is regrettable that few cellular and molecular biologists take advantage of kinetics experiments in their work. Fortunately, the kinetics experiments that are most useful for understanding cellular systems are within reach for everyone whose research would ...

We obtain lower and upper bounds on the skewness and kurtosis associated with the cycle completion time of unicyclic enzymatic reaction schemes. Analogous to a well-known lower bound on the randomness parameter, the lower bounds on skewness and kurtosis are related to the number of intermediate states in the underlying chemical reaction network. Our results demonstrate that evaluating these hig...

We explore the means by which immobilization of a substrate on a surface can increase the rate of a diffusion-controlled enzymatic reaction. A quasichemical approach is developed and compared with Brownian dynamics simulations. We use these methods to show that restricting only the orientation of the enzyme by long-range interactions with the surface is sufficient for enhancing catalysis.

Recently, we described a pathway analysis technique (paper 1) for analyzing generic schemes for single-molecule kinetics based upon the first-passage time distribution. Here, we employ this method to derive expressions for the Poisson indicator, a normalized measure of stochastic variation (essentially equivalent to the Fano factor and Mandel's Q parameter), for various renewal (i.e., memoryles...
